| | Darwin, Mach, BSD. Who does what (Site not responding. Last check: 2007-10-05) |
 | | Darwin, which comprises the underpinnings for Mac OS X, is "Mach", "BSD", and "IOKit". |
 | | IOKit is the device driver support component of Darwin; BSD is the primary "OS"; and Mach is used to provide memory management, process/task/thread support, and messaging. |
 | | Darwin is, for all intents and purposes above the very low levels of the OS implementation, BSD. |
